Talk about getting sacked!

Notorious Upper East Side madam Anna Gristina is about to start naming names of high-power clients from her little black book — and an unlucky NFL executive will be the first bombshell name she lets fly, we’re told.

“There is going to be a giant name dropped — actually, a couple of them,” Gristina told The Post’s Laura Italiano, speaking of her plans for an upcoming interview with TV host psychologist Dr. Phil.

Asked if those names would be “giant” with a capital “G,” the Hockey Mom Madam gave a distinctly mischievous laugh that portends bad news for the bigwig client.

“Everyone’s going to have to watch Dr. Phil,” she said. “I will tell you that one of the names is high-level [NFL] management. Then there’s an older [football] player who’s still very well known. Tune in to Dr. Phil!”

Gristina spoke yesterday after making a brief reappearance before Manhattan Supreme Court Justice Juan Merchan, the same judge who earlier this year set her bail at $2 million on a single count of promoting prostitution.

But this time around, Merchan’s ruling was more favorable to Gristina — allowing the Scotland-born mother of four, over DA objections, to fly to Los Angeles next week so the Dr. Phil taping can go forward.

Last month, Gristina was sentenced to six months in jail followed by five years of probation. And she’s now in the midst of transferring the probation stint from New York City to closer to her home in upstate Monroe. She had been barred from leaving the city until her new, local probation officer was assigned.

“I don’t see how anyone is harmed” by her traveling to LA, explained the judge, who might not have been aware of Gristina’s talking points on the upcoming Dr. Phil episode.

The taping is scheduled for Wednesday or Thursday of next week, Gristina says, and should air about a week later — just in time for the holidays.
